At present, the surface of domestic thin steel plates mainly suffers from scratches, rust, pits and poor cleanliness, and some materials coated with anti-rust oil are difficult to clean. In addition, due to insufficient flatness of the steel plate, slip lines appear after some materials are stamped ...
With the increase in strength of steel materials, martensite is used in various steels. However, because the martensite structure is fine and complex, and the strengthening mechanism is not simple, it is very complicated to find out the mechanism to increase the strength ...
One of the most important issues for the development of 700 ℃ steam temperature A-USC generator sets is the development of heat-resistant alloys for turbine impellers. Some researchers have developed Ni-0.05C-18Cr-13Co-9Mo-1.3Al-1.4Ti-0.1Ta-0.3Nb alloy based on Inconel 617 as the basic material and ...
Based on the comprehensive consideration of cost and mechanical properties, expanding the application of aluminum alloy is currently the main means of reducing the weight of passenger cars and reducing fuel consumption. For example, the engine cylinder head is now fully made of aluminum alloy. Altho ...
Successful precision casting manufacturers know the importance of process control for the production of high-quality castings. The key variables in the casting process include the mold temperature, the thermal insulation properties of the mold, the cycle time and the method of the operator, etc. How ...
Different types of steel are used as plastic molds, and their chemical composition and mechanical properties are different, so the manufacturing process routes are different; similarly, different types of plastic mold steels use different heat treatment processes. This section mainly introduces the ...
The shaft sleeve is one of the main parts of the gear pump. It is installed on the two ends of the high-speed gear to support the bearing. It must have sufficient strength and good wear resistance. In order to ensure the performance requirements of the parts, our factory uses non-standard aluminum-t ...
Oxygen and nitrocarburizing treatment can be carried out in a pit carburizing furnace, using liquid ammonia, oxygen and nitrogen as infiltrating agents. The inner wall of the furnace pot, the inner surface of the furnace cover and the loading frame are all coated with water glass graphite paint and ...
Usually the drawworks brake system is composed of main brake and auxiliary brake. As the key force component of the main brake of the drawworks brake system of drilling rigs and workover rigs, brake hubs are under severe stress conditions and are easily damaged. ...
Due to the high quality requirements of automobile wheels, its structure is suitable for low-pressure precision casting, and the demand is large, it has greatly promoted the development of low-pressure casting technology. At present, low-pressure casting has become the main process method for the pr ...
Melt leakage will not only affect the quality of plastic parts, but also severely damage the mold, resulting in failure to produce. There are two main leaking parts of the hot runner mold, one is the end face of the runner on the runner plate, and the other is the junction surface of the runner plat ...
